LUBRICATING BOLT FOR THE SPBIN G SHACKLES 0F AUTOMOBILE VEHICLES.

Application filed June 17,

To all whom it may concern: Be 1t known that I, ALFRED ERNEST LEON SECQUEVILLE, a citizen of the French Reublic, and residing at Gennevilliers, Seine, rance, have invented certain new and useful Improvements in Lubricating Bolts for the Spring Shackles of Automobile Vehicles, of which the following is a specification.

The present invention has for its subject a lubricating bolt particularly applicable as the shackle bolt for springs of automobile vehicles. The invention is characterized b the' provision of conical split rings mounted on the bolt of the spring in the plane of the shackles and by the particular construction of the lubricating bolt.

he conical split rings interposed between the bolt and the heads of the shackles are for the purpose of locking the bolt in the shackle by reason of their conical shape, the spring being free on the bolt.

The bolt of the spring forming a lubricating bolt performs particular functions adapted to facilitate the lubrication- It is furnished with a spring cover which closes the lubricating orifice in such a manner as to prevent the egress of the lubricant and the in ress ofdust, dirt and water.

In the accompanying drawing is shown by way of example, a method of construction according to the invention.

Fi ure 1 is an elevation of the improved shacl e.

Figure 2 is a section on the line I-I of Fi re 1, and

igure 3 is a plan view.

As will be seen in Figure 2, conical split rings 3 are mounted in the plane of the shackles between the heads 1 'o the shackles and the body 2 of the bolts. By reason of the conical shape of theserings the bolt is locked in the shackles by tightening the nut Q on the end of the bolt, thuspreventlng any play and'consequently any uneven Wear or tendency to become oval.

The spring 5 is mounted on .-t he bolt 2 in the usual manner. The bolt, provided with Specification of Letters Patent.

a head 6 of reduced section, is pierced along its axis with a passage 7 communicating, in

a well known manner by means of passages y 11 hinged at 12 closes the opening in the sprlng arranged in any suitable bolt 6. manner normally holds the cap ll in the position shown in Figure 2.

The conical split rings forming the characteristic of the invention are also appli cable springs which are not lubricated, and where- 1n a ring of greased asbestos or of ferodo, black leaded or coated with plumbago, is interposed between the steel rings mounted one upon the body of the bolt and the other upon the spring.

The part played by the conical split rings in this case is particularly important for, if the bolt is not locked in the heads of the shackles the bolts of the spring, without lubrication, cannot operate satisfactorily.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is The combination with a shackle having a plurality of eyes each with a conical aperture therein, of a bolt passing through said eyes, said bolt having an axial channel therein and passages leading from the axial channel to the outersurface of the bolt, the

axialchannelrbeing enlarged at one end and screw threaded, a cap hlnged to the.bolt,

means normally holding the cap closed, conical split rings fitting into the conical apertures and around the bolt, and means for tightenin the conical split rings so as to lock the bolt in the shackle.-
